Admission Control Over Internet of Vehicles Attached With Medical Sensors for Ubiquitous Healthcare Applications

Abstract

Wireless technologies and vehicle-mounted or wearable medical sensors are pervasive to support ubiquitous healthcare applications. However, a critical issue of using wireless communications under a healthcare scenario rests at the electromagnetic interference (EMI) caused by radio frequency transmission. A high level of EMI may lead to a critical malfunction of medical sensors, and in such a scenario, a few users who are not transmitting emergency data could be required to reduce their transmit power or even temporarily disconnect from the network in order to guarantee the normal operation of medical sensors as well as the transmission of emergency data. In this paper, we propose a joint power and admission control algorithm to schedule the users' transmission of medical data. The objective of this algorithm is to minimize the number of users who are forced to disconnect from the network while keeping the EMI on medical sensors at an acceptable level. We show that a fixed point of proposed algorithm always exists, and at the fixed point, our proposed algorithm can minimize the number of low-priority users who are required to disconnect from the network. Numerical results illustrate that the proposed algorithm can achieve robust performance against the variations of mobile hospital environments.

Internet of Vehicles Information Processing Method with Vehicle-Mounted Cloud Grid as the Underlying Data Fusion Structure

“…rough the analysis and study of data transmission characteristics of railway train control in literature [28], the importance of fusion technology to improve safety performance of train control is clearly identified. In this regard, the colored Petri net (CPN) algorithm is used for modeling, and the experimental results show that this method is effective and feasible.…”

Internet of Vehicles: Architecture, services, and applications

“…Ning et al 50 Reliable service access system, emphasize priority, efficiency in response time More resource consumption, complexity because of priority management Simulation information technologies in different domains that can be developed for health monitoring based on sensor information, energy consumption control, and data collection. [67][68][69][70][71] Several applications are used in traffic management. These systems are presented for various reasons, such as economic purposes (e.g., energy management, improvement of public transportation, and public transportation systems improvements) and environmental purposes (e.g., air pollution prevention and monitoring).…”

“…In this case, it is necessary to prioritize users. Lin et al 68 used admission control algorithms to cover the low discontinuation time for high‐priority requests. This algorithm helps to prioritize requests and improve management and efficiency.…”

“…These applications, mainly for intelligent transportation improvements, include routing systems, road surface control systems, parking lights, and parking control systems 35,57,64–66 . The third category includes systems that have consumptions in information technologies in different domains that can be developed for health monitoring based on sensor information, energy consumption control, and data collection 67–71 …”
